397cd31f01 target/arm: Create timers in realize, not init
The timer_new() function allocates memory; this means that
if we call it in the CPU's init method we would need
to provide an instance_finalize method to free it. Defer
the timer creation to the realize function instead.

This fixes a memory leak spotted by clang LeakSanitizer
when a CPU object is created for introspection.

0012eb98f1 tests/test-arm-mptimer: Don't leak string memory
The test-arm-mptimer setup creates a lot of test names using
g_strdup_printf() and never frees them. This is entirely
harmless since it's one-shot test code, but it clutters
up the output from clang's LeakSanitizer. Refactor to
use a helper function so we can free the memory.

c0983085d1 hw/sd/sdhci: Don't leak memory region in sdhci_sysbus_realize()
In sdhci_sysbus_realize() we override the initialization of
s->iomem that sdhci_common_realize() performs. However we
don't destroy the old memory region before reinitializing
it, which means that the memory allocated for mr->name in
memory_region_do_init() is leaked.

Since sdhci_initfn() already initializes s->io_ops to
&sdhci_mmio_ops, always use that in sdhci_common_realize()
and remove the now-unnecessary reinitialization of the
MMIO region from sdhci_sysbus_realize().

Spotted by clang's leak sanitizer.

ac87e5072e target/arm: Free name string in ARMCPRegInfo hashtable entries
When we add a new entry to the ARMCPRegInfo hash table in
add_cpreg_to_hashtable(), we allocate memory for tehe
ARMCPRegInfo struct itself, and we also g_strdup() the
name string. So the hashtable's value destructor function
must free the name string as well as the struct.

Spotted by clang's leak sanitizer. The leak here is a
small one-off leak at startup, because we don't support
CPU hotplug, and so the only time when we destroy
hash table entries is for the case where ARM_CP_OVERRIDE
means we register a wildcard entry and then override it later.
